A

The best way to find out the maximum writing speed of your hard disk is to run writing tests with a single large block of different block sizes:

sqlio -LS -kR -i1 -f1 -t1 -s30 -p0 ...

If we run SQLIO with above options and different block sizes, we should be able to find the maximum writing speed:

             Throughput   Throughput   Latency
Block Size      MBs/sec      IOs/sec        ms
----------   ----------   ----------   -------
       -b8         1.21       155.67         5
      -b16         2.32       149.09         6
      -b32         2.86        91.70        10
      -b64         3.14        50.24        19
     -b128         2.97        23.82        41
     -b256         0.43         1.75       568

As you can see, the maximum writing speed, 3.14 MBs/sec is reached with a block size of "-b64", or 64 KB.

Comparing to the maximum reading speed of 15.36 MBs/sec, the maximum writing speed of 3.14 MBs/sec is about 5 times slower.
